Abstract:

Objective To investigate the prognostic assessment roles of miR-924 and solute carrier family 1 member 5(SLC1A5) in lung cancer tissues. Methods From February 2018 to February 2019,97 lung cancer patients from Nanyang Central Hospital were enrolled,and the general data and cancer and adjacent tissues(>2 cm from tumor edges) were collected. The miR-924 and SLC1A5 mRNA and SLC1A5 expressions were determined. The correlation between miR-924 and SLC1A5 mRNA was analyzed by Pearson correlation analysis. Kaplan-Meier survival curve was used,and Cox regression analysis was used to analyze the risk factors for the poor prognosis of lung cancer patients. Results Compared with adjacent tissue group,the relative expression level of miR-924 in cancer tissue group was decreased(P<0.001),while that of SLC1A5 mRNA and the positive rate of SLC1A5 were increased(P<0.001). The miR-924 expression was negatively correlated with SLC1A5 mRNA in lung cancer tissue(r=-0.843,P<0.05). The research subjects were classified into high-expressed group,low-expressed group and positive group,negative group according to the mean value of miR-924 relative expression level or the expression of SLC1A5,respectively. There was statistical significance in the differentiation degree and clinical stage between miR-924 low-expressed group and high-expressed group and between SLC1A5 positive group and negative group(P<0.05). The cumulative survival rate of miR-924 high-expressed group was higher than that of miR-924 low-expressed group(Log-rank χ2=5.453,P<0.05),and the cumulative survival rate of SLC1A5 positive group was lower than that of SLC1A5 negative group(Log-rank χ2=9.259,P<0.05). Clinical stage Ⅲ,low expression of miR-924 and positive SLC1A5 were risk factors for poor prognosis of lung cancer patients(P<0.05). Conclusions The lung cancer patients has abnormal expressions of miR-924 and SLC1A5 in cancer tissue,which are expected to become the markers for evaluating lung cancer prognosis.
